Guangdong Zhongshan E2K-X4MEI Contactless Proximity Switch Wiring Diagram Proximity Switch Introduction: Proximity switches, also known as contactless proximity switches, are electronic switch quantity sensors. When the metal detection body approaches the sensing area of the switch, the switch can quickly issue electrical commands without contact, pressure, sparks, and accurately reflect the position and travel of the moving mechanism. Even when used for general travel control, its positioning, operating frequency, service life, convenience of installation adjustment, and adaptability to harsh environments are incomparable to general mechanical travel switches. It is widely used in industries such as machine tools, metallurgy, chemicals, light textiles, and printing. In automatic control systems, it can be used as a limiting, counting, positioning control, and automatic protection link. Proximity switch is a type of switch type sensor (i.e. contactless travel switch) that has the characteristics of travel switch and micro switch, as well as the performance of sensors. It has reliable action, stable performance, frequency response, long service life, strong ability, waterproof, shockproof, corrosion-resistant, and other characteristics. It is widely used in industries such as machine tools, metallurgy, light textiles, and printing. In automatic control systems, it can be used as a limiting, counting, positioning control, and automatic protection link& nbsp; The basic classification is that displacement sensors can be made according to different principles and methods, and different displacement sensors have different effects on objects; lquo; Perception; rquo; The methods are also different, so there are several common proximity switches: passive proximity switches, which do not require power and control the closed state of the switch through magnetic induction. When a magnetic or iron trigger approaches the switch magnetic field, it is controlled to close by the internal magnetic force of the switch. Features: No power required, non-contact, maintenance free, environmentally friendly. Eddy current proximity switches are sometimes also called inductive proximity switches. It utilizes a conductive object to generate eddy currents inside the object when approaching a proximity switch that can generate an electromagnetic field. This eddy current reacts on the proximity switch, causing changes in the internal circuit parameters of the switch, thereby identifying whether a conductive object is moving closer and controlling the on or off of the switch. The object that this proximity switch can detect is a conductive body. The measurement of a capacitive proximity switch is usually based on one electrode that forms the capacitor, while the other electrode is the outer shell of the switch. This casing is usually grounded or connected to the equipment casing during the measurement process. When an object moves towards a proximity switch, regardless of whether it is a conductor or not, its proximity always causes a change in the dielectric constant of the capacitor, resulting in a change in capacitance and a change in the state of the circuit connected to the measuring head. This can control the connection or disconnection of the switch. The objects detected by this proximity switch are not limited to conductors, liquids or powders that can be insulated. Hall proximity switch Hall element is a magnetic sensitive element. A switch made using Hall elements is called a Hall switch. When a magnetic object moves close to a Hall switch, the Hall element on the detection surface of the switch produces a Hall effect, causing a change in the internal circuit state of the switch, thereby identifying the presence of a nearby magnetic object and controlling the on or off of the switch. The detection object of this proximity switch is a magnetic object. A photoelectric proximity switch is a switch made using the photoelectric effect and is called a photoelectric switch. Install the light-emitting device and photoelectric device in the same detection head in a certain direction. When a reflective surface (the object being detected) approaches, the photoelectric device receives the reflected light and outputs the signal, thus allowing for; lquo; Perception; rquo; There is an object approaching. Inductive proximity switch 1. Principle: It consists of an inductor coil, capacitor, and transistor to form an oscillator, which generates an alternating magnetic field. When a metal object approaches this magnetic field, eddy currents are generated inside the metal object, causing the oscillation to stop. This change is amplified by the back pole and converted into a transistor switch signal output. 2. Features: A. Good performance, switching frequency, greater than 200Hz B、 Can only sense metals. It is applied to various mechanical equipment for position detection, counting signal pickup, etc. Guangdong Zhongshan E2K-X4MEI Contactless Proximity Switch Wiring Diagram Shandong Zhuoxin Machinery Co., Ltd.
